I should've added:
I'm building the lily58 pro
The two halves are Supermini nrf pro micros
The two halves' OLED displays are those 0.91inch ones I got off aliexpress, and I've tested and both of them work(as well as I've got a couple of spares)
The dongle is a seeeduino xiao ble.
The dongle's oled screen is a 128x64 SH1106

Ive also checked the SDA and SCL pins on the xiao and they're correctly connected. I really dunno what's wrong ;-;

#

I've tried playing around with the shields, revert back to both zmk-config and zmk-dongle repositories, change the xiao dongle .overlay to use the sh1106, but alas it yielded nothing.

Are those standard headers on the Xiao? They look like they haven't been soldered to it; if they aren't, they aren't connected.
I'd focus on making sure the basics work before adding display modules and dongles
Regarding the OLED on the right half:

Just in case it wasn't clear:

  • The peripheral half (the right, by default) of your keyboard only ever sends keystrokes over BLE to the central half. It will not output over USB or pair to a computer/phone/etc.
  • When you introduce a dongle, both halves of the Lily will become peripherals. The dongle becomes the central.

This means:

  • You're going to need to modify the configuration on the halves, even if you use some other repository for the dongle.
    • Note the ⚠️warning box on that page.
  • The halves will not really work unless they are connected to the dongle via BLE. (You won't be able to type with them, that is.)
  • The halves will both show the "peripheral" displays.

Ok, so the dongle display does work, and now only the right half's display doesn't work.
I am trying to look at other's configs to see what I might be missing. There is voltage on the display
